A nurse is caring for a client who has acute angina. Which of the following actions should the nurse take first?

Choice A reason: Injecting the medication into the abdomen above the level of the iliac crest is not recommended. The preferred sites for subcutaneous injections are the fatty tissue over the triceps, the abdomen from below the costal margin to the iliac crests, and the anterior aspects of the thighs. The area above the iliac crest may not have sufficient subcutaneous tissue, which could affect the absorption of the medication.

Choice B reason: Using a 1-inch needle can be appropriate depending on the client's body mass. For most adults, a 5/8-inch to 1-inch needle is recommended for subcutaneous injections to ensure the medication is delivered to the subcutaneous tissue and not into the muscle.

Choice C reason: Using a 25-gauge needle is the appropriate action when administering heparin subcutaneously. A smaller gauge needle, such as 25-gauge, is typically used for subcutaneous injections to minimize discomfort and tissue trauma.

Choice D reason: Massaging the injection site after administration of the medication is not recommended when administering heparin subcutaneously. Massaging the site can cause the medication to be absorbed more quickly than intended and may increase the risk of bleeding.

Choice A reason: Gurgling bowel sounds every 10 seconds are considered normal, as normoactive bowel sounds range from 5 to 30 sounds per minute. This finding indicates regular gastrointestinal activity and is not typically a cause for concern.

Choice B reason: A centrally located umbilical protrusion can be a normal finding, especially if it has been present since birth and is not associated with any other symptoms. However, if new or associated with pain or other symptoms, it could indicate a hernia or other pathology.

Choice C reason: Abdominal distention during breathing can be a normal finding, as the abdomen may distend slightly during deep breathing due to the movement of the diaphragm. However, if the distention is pronounced or associated with other symptoms, it may warrant further investigation.

Choice D reason: Rebound tenderness with palpation is a sign of peritoneal irritation and can be an indication of conditions such as appendicitis, which is a surgical emergency. This finding should be considered a priority as it may require immediate intervention.
